TRICK WRITING IMPLEMENT.

Specification of Letters Patent.

Patented Sept. 14, 15915.

Application filed May 28, 1914, Serial No. 841,672. Renewed June 23,1915. Serial No. 35,942.

To all whom it may concern Be it known that I, ARTHUR MEYER, merchant, asubject of the King of Prussia, and residing at StallschreiberstrasseNo. 58, Berlin, S. H, Germany, have invented certain new and usefulImprovements in Trick VVi-iting Implements, of which the following is aspecification.

The present design consists in a trick writing-implement serving as adevice for a practical joke, which is constructed in such a manner thatwhen used for writing it falls apart owing to the action of a spring,and in this way creates a surprise.

An example of construction of the design as a writing pencil isillustrated in the accompanying drawings.

Figure 1 shows the pencil in the assembled condition ready for using.Fig. 2 a longitudinal section through the same, in which the position ofthe parts immediately after falling apart is indicated in dotted lines.Fig. 3 a cross section through the pencil.

As shown in the drawings, the stem or barrel of the writing pencilconsists of two longitudinal halves a and 1), between which a spring 0is inserted which tends to force the two halves apart. The two parts aand Z) of the stem are held together by caps, casings or the likeengaging over the ends. The one cap (Z can at the same time be fixed toone half Z) of the stem, for example, a plate may be soldered on. Theother casing or cap is formed by the point portion 6, which at the sametime carries the lead, pen-nib or the like. This point portion 6 is withits cap 7 pushed loosely over the two halves so that it is held uponthese by the pressure of the spring 0 which tends to move the two halvesof the stem apart. Now, if such a writing implement is taken in the handin order to write, upon this attempt to use the same the point portion 6is lifted sidewise releasing the ends of the two halves a and b of thestem which are forced apart by the spring 0, as is indicated in dottedlines in Fig. 2.

Instead of the point e for blacklead penoil, as illustrated, the frontpart of a writ ing pen can also be employed. Also a removable cap orcasing can be placed upon this in order to protect the lead, as has beenusual many times before, and the two halves of the stem may be heldtogether by this means. In this case the springing apart of the halvesof the stem will take place when the protecting cap is. withdrawn.

As is shown in the drawings, the present example of construction isformed of sheet metal; it can, however, be made in practice also in anyother desired suitable material. Similarly the same can be assembledfrom a plurality of longitudinal parts instead of from two which areforced apart by a spring.

The spring 0 can be so arranged that it is connected with the two partsa and b of the stem in. any suitable manner to form a hinge so that whenthe two parts are forced apart they are still connected by means of thespring.

As shown in the drawing the spring may consist of two legs lyingalongside each other and a coil or bend connecting them. the foot of oneleg being bent around a cross bar fixed in the one member (6, and thecoil or bend encircling a cross bar or pin fixed in the other member 5,the free leg of the spring bearing against the inner face of the memberZ).

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to beperformed, I declare thatwhat I claim is 1. A trick writing implement with a stem consisting ofseparated members, removable caps pushed on at either end and a springunder tension arranged in the interior of the stem, forcing asunder thedifferent members when released.

2. A trick writing implement with a stem consisting of severallongitudinal members, two caps keeping together the said members againstthe tension of a spring, one cap being attached to one of thelongitudinal mem bers, the other one being connected to a lead K holder.

3. A trick writing implement with a stem consisting of severallongitudinal members, two caps keeping together the said members againstthe tension of a spring, one cap being attached to one of thelongitudinal members, the other one being shaped as a nib holder.

4-. A trick writing implement with a stem consisting of severallongitudinal members, two caps keeping together the said members againstthe tension of a spring, one cap being attached to one of thelongitudinal members, the other one being shaped as protecting cap.
